Nakamura Stainless, based in Pulau Ujong, Singapore, manufactures and supplies high-quality stainless steel products, including stainless steel 310H fasteners. These fasteners are made for high-temperature and high-pressure settings. They offer excellent resistance to oxidation, scaling, and thermal fatigue. Stainless steel 310H is a high-carbon version of 310, which provides more strength and creep resistance at elevated temperatures. Nakamura Stainless focuses on precise manufacturing and strict quality control, making 310H fasteners a dependable choice for industries like power generation, petrochemical, furnace construction, and heat treatment systems.
Stainless steel 310H fasteners consist of 24–26% chromium, 19–22% nickel, and a higher carbon content than standard 310, which improves high-temperature mechanical properties. These fasteners usually provide tensile strength between 520 and 750 megapascals and maintain their structure at temperatures up to 1100°C. The high chromium and nickel content guarantees strong resistance to oxidation and thermal degradation in tough environments.
